Submission of proposition

1. The board may, and upon the written request of one hundred eligible electors or a number of electors which equals thirty percent of the number of electors who voted in the last regular school board election, whichever number is greater, shall, direct the county commissioner of elections to provide in the notice of the regular election for the submission of any proposition authorized by law to the voters. When the board has directed the commissioner to submit to the voters a proposition authorized by section 278.1, subsection 1, paragraph “g” or “h”, it shall not thereafter direct the commissioner to submit at the same election any other proposition under either of those paragraphs. 2. Petitions filed under this section shall be filed with the secretary of the school board at least seventy-five days before the date of the regular school election, if the question is to be included on the ballot at that election. The petition shall include the signatures of the petitioners, a statement of their place of residence, and the date on which they signed the petition.
